The invention discloses a contaminated soil remediation system. The contaminated soil remediation system comprises: leaching equipment, which comprises a reagent tank, a leaching injection device andan injection well, wherein the reagent tank can store at least one of a surfactant and hydrogen peroxide, the injection well extends into contaminated soil, and the leaching injection device can convey a solution reagent in the reagent tank to the injection well; and extraction equipment, which comprises a suction device and an extraction well, wherein the extraction well extends into the contaminated soil, the suction device is connected with the extraction well, and a leaching interval is formed between the injection well and the extraction well. According to such a scheme, the problems thatpollutant extraction efficiency is low, extraction cost is high and secondary pollution is likely to occur in existing contaminated soil remediation processes can be solved. The invention further discloses a contaminated soil remediation method.
Description
Technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to a contaminated soil remediation system and a method for remediating contaminated soil. Background technique [0002] As an important energy source, petroleum is widely used in industrial production. Leakage accidents are unavoidable in the process of oil extraction, processing, transportation, storage and utilization, causing soil petroleum hydrocarbon pollution. The water solubility of petroleum substances is generally very small, and soil particles are not easily infiltrated by water after adsorbing petroleum substances, which reduces soil water permeability, water permeability, and air permeability, and changes the composition and structure of soil organic matter, causing soil organic matter Changes in the ratio of carbon to nitrogen and carbon to phosphorus, and also pollute groundwater. Cause great harm to the natural environment, and even harm people's dr...
